A New Method of Studying the Performance of Grinding Wheels

Abstract

A new technique for studying the performance of abrasive tools is described that is not only useful for evaluating the rate of wear of grinding systems but is also capable of yielding difficult to obtain data (such as the effective number of cutting points and local wheel work deflection) essential in fundamental studies of grinding. The new method involves overcut fly cutting with a small (1/8 in × 1/8 in) cluster of abrasive grains that are normally bound together and dressed. The small size of the specimen is particularly important relative to wear studies in that it enables wear data to be obtained with a relatively small amount of grinding and also permits the used abrasive to be studied in the scanning electron microscope.
